Title: Power amplifier
Inventor: SHIYOUJI MASASHI
IPC: H03F3/20
Filed: 1978-07-10
Abstract: PURPOSE:To secure the normal operation for the push-pull circuit of the output step by giving control to both the base potential of the transistor which supplies the signal and the base potential of the transistor of the next step. CONSTITUTION:The amplifier circuit consists of emitter follower transistor 12, Tr14 and 15 forming a differential amplifier, Tr22 forming a preamplifier, Tr25 and 26 forming a complementary Tr, and others. In such amplifier circuit, the base of Tr12 is connected to input terminal 2 through resistance 7, and the emitter is connected to the base of Tr14 via backward diode 10. In case the negative excessive signal is applied to terminal 2, the forward collector-base current of Tr12 is supplied through resistance 7. Thus the base potential is controlled to the lower level than the collectorpotential as well as heighten the base potential of Tr14 with a level shift equivalent to the forward voltage amount of diode 10. As a result, Tr14 is never saturated, and accordingly the nonconductive state or insufficient driving is never given to Tr22 and 26. And therefore, no abnormal output waveform is produced.

Title: Door for incinerating furnace and window for air-intake for incinerator
Inventor: HARIO YASUO
IPC: F23G5/50
Filed: 1996-04-05
Abstract: PROBLEM TO BE SOLVED: To prevent injection of an explosion flame following explosion of incomplete combustion gas by a method wherein a heat resistant flap panel is arranged at the window hole of a door for an incinerator and the window hole is closed by the flap panel by a gas flow pressure over a given value, flowing from the inside to the outside of the incinerator. SOLUTION: When, during combustion of a substance to be incinerated, a large quantity of new substances to be incinerated are charged at one time, flame at the internal part of an incinerating chamber dies out due to deficiency in oxygen in the incinerating chamber. In this case, the substance to be incinerated is brought into an incomplete combustion state and the incinerating chamber is full of incomplete combustion gas. When the gas is ignited with flameless remaining fire or pilot and small explosion occurs in the incinerator, an air pressure accompanied with an explosion flame form an internal part due to the small explosion causes oscillation of the flap panel 23 in the direction of a window hole 25, and the tip part thereof is pressed against a stopper surface 24.  In this way, the flap panel 23 closes the window hole 25 to prevent injection of an explosion flame and a foreign matter. When the small explosion is out, and a gas flow pressure exceeding a given value from the inside of the incinerator to the outside does not exist, the flap panel 23 is brought into an original suspending state and a window hole 25 is opened.
